(9.1) A nimbus we shall call sense of time gives the perception of any and all changes we experience from their sentience. Without change, the perception of time itself is impossible. We say, for example, that we sense the passage time since the sun rose at sunrise. Yet have we woken up at noon, we would not sense the passage time since the sun rose at sunrise. That is, our sense of time is an illusion of the mind.

(9.2) We shall call time itself an immaterial and indivisible continuum in which changes in the material world around us occurs.

(9.3) The point in time in which is now is we shall call time present.

(9.3.1) Time present is not universally the same for all things, including all unus. Indeed, what is time present for one may be time past or time future for another and vice versa. These differences in time present are small but perceptible by measurement in everyday life but can vary widely in the general case.

(9.4) Is only and always exists in time present for unus That is, each unus has a different time present.

(9.5) The point in time from which is has changed we shall call time past. Is does not exist in time past, only in time present.

(9.6) The point in time to which is will change we shall call time future. Is of time present will not exist in time future. Time future will be the result of changes in is from time present.

(9.7) The true nature of time is unknowable.

(9.7.1) Time is insensate and is only the perception of change itself.

(9.7.2) We can have no consciousness of time itself because it has no attributes that can be sensed.

(9.8) Time, being a nimbus is incapable of being detected through our physical senses of sight, sound, touch, taste and smell, cannot be quantified in and of itself. It can only be compared to arbitrary intervals of observable changes in things. When these intervals of change repeat uniformly, we shall call them units of time. Units of time, unlike the observable change in matter that produce them, are, of themselves, nimbus. Years, months, days, hours, minutes and seconds are examples of units of time, all of which are referenced to a standard measurement of time. The year has been traditionally taken as the unit of time for the earth to rotate around the sun. The second has traditionally been taken are as 1/86400 of a day but is now taken as a standard by a measure of 9,192,631,770 cycles of the unperturbed ground-state hyperfine transition frequency of photon release from the cesium 133 atom. The inventors of clocks understood the concept of time correctly, but 2000 year ago the best measurement of units of time was with a water clock known as the clepsydra (water thief) used as a stop-watch for imposing a time limit on client's visits in Athenian brothels. it was only accurate to a gain or lose about half an hour per day.

(9.9) Is is independent of time and does not require time for its existence. Is is only subject to change.

(9.9.1) Proof of the existence of the material world as we understand it does not require the existence of time. Time is associated only with changes in the material world as we know it.

(9.10) Time exist as a false perception, held as false knowledge.

(9.10.1) Time intervals (not to be confused with units of time do exist as changes in the matter of the physical word and might alternatively be call intervals of change.

(9.10.2) Intervals of change in a thing may itself change relative to intervals of change in another thing. That is, while time is continuous it is not constant. This is a property of the physics of relativity of 4-dimensional space. It is, for example, why the intervals of time as measured by GPS satellites in outer space must be correct to coincide with the different intervals of time as measured on the surface of the earth if we are to accurately know where you are on earth using GPS signals. If left uncompensated, the relative difference would cause navigational errors that accumulate faster than 10 kilometers (about 6 miles) per day. With corrections for relativity, the errors can be as small as few millimeters (about 1/10 of an inch). Indeed, current (2022) cell phones have GPS that are accurate to about 25 centimeters (about 1 foot).

(9.10.3) Time is absolute but only so for each observer of change.

(9.10.4) A thing said to be in a quantum state of existence can simultaneous have the properties of this, that, and a combination of both this and that can also have two different intervals of change simultaneously in the same thing. This phenomenon has application in quantum computing.

(9.11) Time is ethereal and humans are notorious poor at estimating intervals of time. Tests of estimation by humans of time intervals for them to perform a complete a task have been found to be in error by as much or more than 100%. Who has not said that they lost track of time when preoccupied with something?

While the human body has numerous biological clocks, we can gain no perception of time or time intervals from them. As an example, we only know when our biological feeding time clock triggers the emotion of hunger at a point of time we usually have lunch. When we undergo a change from daylight savings time to standard time, however, our feeding clock typically takes a time interval of a week or so to reset itself.

(9.12) Time is not essential for the existence of is. Indeed, time is neither an element of, nor necessary for proof of, the subatomic world of elementary particles. Indeed, changes in the subatomic world can and do occur without the passage of any time interval at all. An everyday example of this is the forces in the electric field that cause the sensation of touch. As you press your finger harder against a tabletop, the forces caused by the repulsion of the subatomic particle we call electrons in the electric field in your finger and the electric field in the table change instantaneously, without the passage of time. The sensation felt in your mind and caused by these forces does not occur instantaneously however, as the electrochemical changes necessary to transmit the sensory signal generated in your finger to your brain occur over a small but measurable time interval.

(9.12.1) Matter said to be in a quantum state of being that is simultaneous this or that or a combination of both this and that can also appear to have two simultaneous states of time.

(9.13) Time is an element of neither is nor reality but time can be euphemistically said to be what prevents everything from happening at once.

Summation

(9) Time does not exist in the physical world except as changes in the physical world. Time is insensate to unus and exists only as a false perception of reality in the mind. Intervals of change are relavisitic and depend upon each observer of change.
